J. R. Betancourt, Improving Quality and Achieving Equity: The Role of Cultural Competence in Reducing Racial and Ethnic Disparities in Health Care, The Commonwealth Fund, October 2006
The 2001 Institute of Medicine (IOM) report, Crossing the Quality Chasm, highlights a significant gap between the quality of health care people should receive, and the quality of care they actually receive. But it is important to consider more than just provision of recommended care in determining health care quality. There is growing recognition that—in addition to being based on the best available scientific evidence—health care should also be easy to navigate, safe, accessible, and responsive to patients' needs. Countless studies, culminating in another influential IOM report, Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care (2002), have found that people of color often receive a lower quality of care than their white counterparts—even when insurance and socioeconomic status, comorbidities, stage of presentation, and other factors are taken into account.
This report identifies aspects of cultural competence that are synergistic with current efforts to develop a system that delivers higher-quality care and discusses strategies by which the quality and cultural competence movements could be linked.
Cultural Competence and Health Care Quality
To understand how cultural competence ties into efforts to address disparities and improve general health care system quality, it is helpful to carefully examine the six IOM principles of quality.
Safety: According to the IOM, patient safety is not solely about addressing general systems issues to prevent the failure of a planned action to be completed as intended or the use of a wrong plan to achieve an aim (such as administering the wrong medication or dosage). It also entails: avoiding misdiagnosis, preventing patients from exposure to unnecessary risks; and ensuring informed consent. Unequal Treatment highlighted the importance of improving provider–patient communication as a method of addressing racial/ethnic disparities in health care. In particular, the report recommended that health care providers be trained in cross-cultural communication and that health care systems support the use of interpreter services for patients with limited English proficiency. Improved communication through such means has the potential to: improve the capacity of health care providers to make accurate diagnoses; prevent patients from exposure to unnecessary risks from diagnostic procedures (particularly where language barriers play a role); enable providers to obtain truly informed consent; and allow patients to participate in clinical decision-making.
Effectiveness. Crossing the Quality Chasm highlights the importance of using evidence-based guidelines to provide high-quality care. It defines "evidence-based practice" as the integration of the best research evidence with clinical expertise and patient values. Two aspects of cultural competence—systemic and clinical—can play a role in improving effectiveness. First, in order to ensure effective care, systems must be in place to detect health disparities by stratifying measures by race/ethnicity. Use of interpreter services as a vehicle for improving communication is also essential. Second, clinical cultural competence, which includes health care providers' ability to ascertain patient preferences and values, is a clear component of effectiveness.
Patient-centeredness. Crossing the Quality Chasm states that compassion, empathy, and responsiveness to the needs, values, and expressed preferences of the individual patient are the hallmarks of patient-centeredness. Many would agree that these attitudes and skills are also central to clinical cultural competence.
Timeliness and efficiency. Crossing the Quality Chasm states that a timely system is one that prevents patients from experiencing harmful delays in receipt of necessary services, and that an efficient system is one that avoids quality and administrative waste. Language barriers may contribute to increased length of stay in the hospital or longer wait times in an emergency department. Systemic cultural competence could thus improve the timeliness and efficiency of a system by getting patients the services that are appropriate in an expeditious fashion.
Equity. Crossing the Quality Chasm states that a system is high quality if it provides care that does not vary because of personal characteristics such as gender, ethnicity, geographic location, and socioeconomic status. Systemic cultural competence, which entails processes to monitor the quality of care and detect disparities by stratifying measures by race/ethnicity, would lay the foundation for targeted quality improvement activities.
Quality Improvement Approaches
Specific quality improvement approaches, such as disease management (DM) and the chronic care model (CCM), have typically operated in "cookie-cutter" fashion, relying on technology, telephone contacts, and case management. A review of the key principles of CCM and DM identifies areas where cultural competence could be embedded.
Quality, Cultural Competence, and Disparities: A Framework
This analysis presents a framework to consider the interplay among cultural competence, quality, and racial/ethnic disparities in health care. It presents hypothetical interventions based on evidence, as well as evidence of strategies that have been found to work. The framework, presented in Table ES-1, explores the root causes of disparities, how cultural competence might address them, and what other approaches outside of cultural competence are needed. Any efforts to address racial/ethnic disparities must be predicated on effective, standardized collection of race/ethnicity data, stratification of those data by race/ethnicity, and commitment to developing interventions to address disparities if and when they are found.
